To calculate minimum value, do -b/2a to get the x-value, and plug it in to get the y-value:

-6/8 = -3/4

$4 * (-\frac{3}{4} )^{2} + 6 (-\frac{3}{4} ) - 18 = \frac{9}{4} - \frac{9}{2} - 18 = - \frac{81}{4}$

So the minimum value of g(x) is -81/4

This shows that g(x) has a lesser minimum value than f(x)

What are the coordinates of the red dot?

kow [346]

Answer:

(5, 2)

Step-by-step explanation:

Coordinates of a point in a coordinate plane is usually written as (x, y). This point contains the value of x and its corresponding y value.

The red dot on the plane given, if you trace it down to the x-axis, it is at x = 5, while if you trace it horizontally against the y-axis, you'd have y = 2.

Therefore, the coordinates of the red dot is (5, 2).
